Warehouse Lighting Solutions - Efficiency Upgrades
The Yusen Logistics warehouse in Wetherill Park, Sydney required a reduction in energy usage to ensure operational viability on a financial, ecological and compliance perspective. The lighting within the building was outdated, assessed as non-compliant to minimum Australian AS1680 standards and the luminance had decreased over time.
A thorough review of the lighting requirement across the 21,800m2 floorspace led to a design using both classic round LED highbays and linear LED highbays. Using the longer fittings with an elongated beam spread in the storage aisles allowed a significant reduction in the number of luminaires required to illuminate the same area and improve the vertical light levels. The new design and repositioning required 89 fewer fittings to achieve a significantly improved brightness and even lighting coverage. As a result, the lux levels increased by up to 8 times in some areas.
On top of the energy savings gained by the reduction of fittings and the highly efficient LED technology, further reductions are achieved through the use of lighting controllers and sensors which monitor area occupancy and natural light from the skylights to adjust the required light levels accordingly.
To maximise the savings, one sensor per light fitting was installed so that every single light (spaced approx 9-12m apart) is individually controlled to suit the unique conditions of that particular area. To reduce installation time/costs, the sensors were connected to each fitting prior to site delivery.
Due to the ever changing light control environment, the savings gained by the use of sensors is a calculation from the on spot post installation lighting circuit load test, held at 10:00 am on 10th April 2015.
